FAN ATTACHBTENT FOB.- CHAIRS.

Specification of Letters Patent.

Application filed May 14, 1909. Serial No. 495,913.

To all whom it may concern:

Be it known that I, LAWRENCE Hinonn'rri, a citizen ofthe United States,residing at Pine Grove, in the county of Clark and State of Kentucky,have invented new and useful Improvements in Fan Attachments for Chairs,of which the following is a specification.

This invention is an improved fan attachment for rocking chairs, adaptedto be readily attached to an ordinary rocking chair and to beautomatically operated thereby when the rocking chair is in motion so tofan the user of the chair and without any exertion on his part otherthan that required to rock the chair and the said invention consists inthe construction, combination and arrangement of devices hereinafterdescribed and claimed.

in the accompanying drawings :-Figure 1 is a side elevation of a fanattachment for rocking chairs constructed in accordance with myinvention, the chair to which the attachment is secured being indicatedin dotted outlines. Fig. 2 is a detail rear elevation of the fanattachment. Fig. 3 is a detail horizpntal sectional view on the planeindicated by the line 33 of Fig. 1. Fig. 4 is a detail sectional view onthe plane indicated by the line et l of F ig. 1. Fig. 5 is a detailvertical sectional view on the plane indicated by the line 55 of Fig. 4.

The fan 1 in accordance with my invention is a blower fan comprising ahead 2, a base 3 and an intermediate flexible connecting portion 1, thehead and base being preferably made of metal or some other rigidmaterial and semispherical in form andthe intermediate portion 4 beingpreferably made of leather, rubber, or other flexible material or fabricand being of cylindrical form with its upper and lower ends securedrespectively around the head and base. The base is provided with anozzle 5 for supplying air to and discharging the same from the fan.

A standard 6 is provided at its upper end with a horizontally disposedarm 7, at the front end of which is a fork 8, the head of the fan beingpivotally mounted in the fork as at 9. An arm 10 depends from the arm 7and an operating arm 11 for the lower portion or base of the fan ispivotally mounted at the lower end of the arm 10 as at 12. Saidoperating arm has a fork 13 at its front end in which fork the base ofthe fan is pivotally mounted as at 1.4;. The rear portion of theoperating arm is provided with a plurality of adjusting openings 15. Iwill now describe means for securing the standards at the back of arocking chair and for actuating the operating arm 11 by the motion ofthe chair.

A bar 16 is provided to extend between and for attachment to the chairrockers at a point in rear of the chair. This bar is longitudinallyadjustable so that it may be attached to the rockers of chairs ofvarying widths and is here shown as comprising a pair of members 17which have upwardly extending portions 18 at their outer ends providedwith depending jaws 19 to bear on the outer sides of the chair rockersand which jaws are provided with cushions 20 to prevent them frommarring the chair rockers. The said members 17 of the longitudinallyadjustable bar are disposed in partially overlapping relation and theiroverlapping portions are provided with longitudinal slots 21. A yoke 22,which is substantially U-shaped, bears on the uppermost member of thelongitudinally adjustable bar and is secured to the members of the saidbar by bolts 28 which extend through the slots 21. The standard 6 has abasenr foot 24L which bears on the said yoke and is also secured theretoby the said bolts 23.

Movable jaws 25 are disposed opposite the jaws 19 and provided withhorizontal arms 26 which bear against the upper sides of and areslidably connected to the members 17 of the adjustable bar 16. Theup-turned portions of said members 17 are provided with screws 27 whichbear against the inner sides of the said inovable jaws 25 and serve, inconnection with the relatively fixed jaws 19 of the bar and the saidmovable jaw 25 to clamp the rockers of the chair firmly between saidjaws 19, 25, and hence enable the bar 16 to be readily attached to ordetached from the chair rockers. The said jaws 25 are preferably alsoprovided with cushions or pads 28. A longitudinally adjustable link 29is provided, in accordance with my invention, which comprises a pair ofpartially overlapping members 30 provided with adjusting slots 81 andalso slidably connected together by means of guide and engaging ears 32.A hook bolt 33 which passes through the slots 31 serves to clamp themembers of the link together and to engage the standard 6 and alsofirmly secure said standard to said link. Straps 3t are connected to theouter ends of the members of the link and are provided with buckles orother similar devices whereby the said straps may be secured to thesides or standards of the chair back so as to secure the link on theback of the chair and hence cause the link to coact with the bar 16 indetachably securing the standard of the fan to the back of the chair.

A pair of levers 36 are fulcrumed on a rod 37 which connects theupstanding end portions of the yoke 22. The front ends of the saidlevers are down-turned and a tappet roller 38 is mounted between them asat 39 and bears on the floor at a point between the chair rockers. Thelevers 36 have their rear ends connected together'by a bar it) and a rodl1 has its lower end pivotally connected to said bar as at 42. A link 43is attached to the upper end of the rod a1 and may be engaged with anyof the adjusting openings 15 of the operating arm 11. It will beunderstood that the motion of the chair causes the levers 36 to rock andthat the connections hereinbefore described between said levers and thearm 11 cause rocking motion to be communicated to said arm, said armserving to move the base of the fan or blower toward and from the headthereof and hence the fan serves to blow a current of air downwardly onthe person in the chair. The length of the stroke of the operating arm11 may be varied by adjusting the link 43 with reference thereto so asto connect the link by the openings 15 to the said arm 11 at any desireddistance from the fulcrum 12 of said arm.

I do not desire to limit myself to the precise construction andcombination of devices herein shown and described, as it is evident thatmodifications may be made therein within the scope of the appendedclaims.

,VVhat is claimed is 1. In combination with a fan having a movableelement a supporting standard for the fan, an operating arm for themovable element of the fan, carried by said standard, means to securethe standard to a rocking chair, said securing means including alongitudinally adjustable bar having means to en gage and grip the chairrockers, an operating lever actuated by the motion of the chair andmounted on said bar and connections between said operating lever andsaid operating arm for the movable element of the fan.

2. In combination with a fan having a movable element, a supportingstandard for the fan, an operating arm for the movable element of thefan, carried by said standard, means to secure the standard to a rockingchair, an operating lever actuated by the motion of the chair-andmounted on said standard securing means and connections between saidoperating lever and the said operating arm of the movable element of thefan.

In testimony whereof I afliX my signature in presence of two witnesses.
